`Specification ofL'etters Patent. Applicaties sled April 12, 1907. serial No. 367,787.

Patented Sept, 3, 1907.

To all whom it 'may concern:

Beit knowuthat I, WINFIELn ScorT PALMEE, a citizen of the United States, residing-at Glenburn, inthe county of Lackawanna and State of Pennsylvania, have ,invented a `new and useful Repair-Clip for Pipes,

Shafts, &c., of which the following is a'specication.

This invention relates to clamping members or clips for monding or coupling pipes, brokerrshafts, masts and the like and has for its objectto provide a strong, durable 'and efficient device of this character bymeans of f which adjacentpipe on the shaft sections'may be temporarily or permanently united.

A further object of the invention -is to provide a sectional clamp adapted to embracethe pipe or shaft sections to be united and provided with seating recesses for theA Ireception of a packing strip, the lower longitudinal edges of each clamp section being inclined or beveled therebyto force the packing in Contact with the pipe sections and thus insure a water and steam tight joint. v I

A further object is to. provide a clip or yoke for snpporting the clamping members in engagement with'the pipe sections ,and further vto provide a key or Wedge for locking the several parts .in operative position.

A still further object of theinvention is to generally improve this class of devices so as to increase their utility, durability and efficiency. i

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure l is a'longitudinal sectional View of a clamp or coupling constructed in accordance with `my invention. Fig. 2 is an end view of the same. v Fig. 3 is a perspective view of the clamping members or sections detached. Fig. 4 is longitudinal sectional view showing the clamp used for uniting adjacent sections of shafting. -Similar numerals of reference indicate'correspon'din'g parts in all of the gures of the drawings.

members 5 and 6 each preferably semi-cylindrical in i The improved device comprises a pair ofclamping form andhaving their inner faces concaved to accommodate the pipe or shaft sections 7.-

Interposed between the clamping members o r sections 5 and 6 and the pipe sections 7 is a packing 8 formed of rubber, asbestos or, other suitable material y the inner longitudinal edges of the clamping members being inclined or beveled as indicated at 9 so that when the clamping members `are placed in position on the pipe sections the inclined edges 9 of the clamping members will force the adjacent edges of the packing strip inwardly in engagement with the pipe sections thereby to insure a water, and steam tight joint between the same.

`Embracing the clamping -members or sections 5 and 4 6is aretaining yoke or clip 10 the closed end of which bears against the intermediate curved portion 1l of the upper clamping member 5 while the spaced arms 12 of said clip or yoke'embracesthe lowersection 6 and are provided with spaced perforations in which is jour' naled a transverse pin'or stud\13. The pin or stud 1.3 is

'provided with an enlarged head 14 and is preferablyv inclined or tapered to facilitate positioning the pin in the openings in the yoke.

Secured to or formedntegral with the lower section 6 is a boss or enlargement 15 having a flat bearing surface 16 for engagement with a locking key or wedge 417, the latterbeing interposed between the pin 13 and the dat bearing surface 16 thereby to clamp the several parts in locked position. 1

The opposite ends of tl1e\clamping members 5 and 6 are preferably inclined so as to permit the retaining yoke or clip 9 to be readily positioned on said clamping members.

In uniting two sections of pipe the clamping members are positioned at the juncture. of said pipe sections and retained in said position" by means of the 'clip or .yoke after which the-`wedge 17 is interposed between -the pin 13 and the flat bearing surface 16 vthus forcing the inclined edges engagement with the packing strip and forcing the latter against the'pipe sections.

In order to remove the clamp it is merely necessary to disengage the locking key or wedge 17 and then renove the pin 13 when the yoke 10 maybe disengaged from the 'clamping members and the latter together with the packing removed from 4the pipe sections.

The convex faces of the clamping members 5 and 6 areNpreferably provided with longitudinal grooves or seats 18 for the reception of a key or spline 19 which engages a corresponding key seat formed in adjacent shaft sections 20 when two or more of said shaft sections are to be united, as best shown in Fig. 4 of the drawing. When the clamp is used for uniting shaft sections the packing is dispensed with, the key 19 being interposed between the sections of shafting and the clamping members, as shown. n

. F1- om the foregoing description it will be seen that there is provided an extremely simple, inexpensive and efficient device admirably adapted f 'r the attainment of the ends in view.

Having thus described the invention whatis claimed 1B.
